Free Text Diff Checker

This is a simple line-based diff, not a character-level or word-level diff — it works well for comparing paragraphs, config files, or lists where changes happen at the line level. For code diffs with precise character-level highlighting, a dedicated code diff tool is more appropriate.

Worked Example

Example: Comparing "Hello world" / "Hello there" (line 1) shows the line as changed, with both versions displayed for comparison.

Method

Simple line-based comparison — splits both texts by line breaks and compares each line by position, flagging matches, removals, and additions.
